Send to Machine Shop or Refresh in House

Hi so i scored a 2000 5.9 magnum for $100 with over 200k miles on it. Ran fine when taken out. Well I tore the engine completely apart and everything is way better than I expected!! I can easily see the cross section cuts on the cylinder walls.

I am dumping alot of money into the chasis of a 72 back half duster that i bought/finishing the build. The car will be a drag car. Should I just rebuild the bottom end in house and put all new bearings in it and hone it myself with a ball hone? Or with 200k should it go to a machine shop.

At the moment I was thinking about doing the bottom end myself and sending the heads to a machine shop so they can check and clean/replace anything. But wanted to get some advice with these magnum motors given the high mileage and that it will be drag raced if sending it to a machine shop is necessary?

Thanks in advance for any advice/input.
